"Master Roshi can you ...." Yamcha then approaches master roshi to ask for a request but he stopped when he saw bulma looking at him.
He wanted ti to train under the legendary martial artist but his current relationship with Bulma is already not a very good situation so he knows that if he asks to the training under the master they will break up.
He decided that he will ask another time.
"When are you guys going to get back to training, " Yamcha asked goku and kurullin.
"Of course " kurullin replied.
"No. I have already taught you all that I can." master roshi said.
"Train on your own and make your path. You are already strong enough to walk on your own." master roshi said.
Although he didn't outright state how proud he is of his disciples it was really obvious what he wanted to say.
"Then I am going to find grandpa's Dragon ball," goku said which shocked all of his friends.
"What's that?" kurullin asked.
"It's the dragon ball that his grandpa left him" white replied.
"Wait how did you know about that?" bulma asked.
"There are a lot of things you people don't know about me" he replied.
"There is no way that I am coming with you." oolong said.
"What about you kurullin?" master roshi asked.
"I am planning to stay with you and continue my training. I still have a long way to go before I can use your Kamehameha " kurullin said.
"I see" master roshi nodded.
"Well then see ya, everyone. I am now going to leave with nimbus." goku said as he picked up his stuff.
"You are leaving already."
Kurullin asked.
"It will be the best if I leave as fast as possible" goku replied.
"What an impatient lad." master roshi said.
"You do know how to use the Dragon radar right, " bulma asked.
"Yes. I know. Well, see ya everyone" he said as he leaves the group behind while he was riding on the nimbus.
"Hey where are you going?" oolong asked as he saw white leaving without saying a word.
He dashed off into the sky ignoring him as he went back to the lookout.
"I can not believe that guy" oolong said.
"I am sure we will meet him again, " Yamcha said.
"Why are you, idiots making it seems like he is moving away. We go to the same school" bulma said as she reminded them.
Back on his way to the lookout.
" Why am I still so weak?" he said to himself.
The truth is he is not weak. It's just he was still inexperienced compared to others that have gone through life and death situations or have more than a decade of experience.
If he was able to find out his true fighting style instead of playing around he might even become more powerful.
Luckily for him, he will be soon allowed to become even stronger as Kami was planning for him to give access to the pendulum room.
